ABSTRACT

The lips are cosmetically very important and are vital for speaking, eating and non-verbal communication. They are formed in part by skin and mucosa. They have a rich blood supply and a complex system of muscles underneath to form many different positions. It is important that the lips should be able to seal completely, otherwise dribbling may result. The upper lip is particularly challenging in this regard because it has subtle curves, hollows and mounds, which may be lost after a repair. Small lesions on the lip may be removed and stitched easily side-to-side, usually in a vertical direction. However, if there is any tension causing distortion then a small skin flap or graft may be preferred. Serious sun damage to the lower lip produces crusty, white areas with a high risk of malignant change. The entire lower lip mucosa can be removed and fresh tissue from within the mouth undermined and pulled forward to reline the lip.
